ZEB certification levels refer to the different levels of energy efficiency a building can achieve according to the Zero Energy Building (ZEB) certification system. The ZEB certification levels include:
1. ZEB-Ready: This level means a building has been designed to be highly energy efficient, but energy generation systems have not yet been installed.
2. ZEB-Net Zero Energy Building: This level means a building generates as much energy as it consumes on an annual basis.
3. ZEB-Net Zero Energy Building+ : This level means a building generates more energy than it consumes on an annual basis and feeds the excess energy back into the grid.
4. ZEB-Off Grid Building: This level means a building is completely self-sufficient and functions independently of the grid, generating all its own energy and managing its own resources.
Note that the ZEB certification system can vary depending on the country or region, but these are the general levels.
